To all whom it may concern.'

Be it known thatl I, RALEIGH J. FniwmcxsoN a citizen of the United States, residin at arion, vin the county of Turner an I State of South Dakota, have invented certain new and useful Improvements in Printing, Develo ing, and Fixing Apparatus, of`

done on paper in cut-sheetcor card form,

suitable mhanism being.- provided for rapidly and eiciently handling the sheets or cards within the machine without the y A danger ofaccidental exposure while passing through the several stages .necessary to thev :reproduction of a` nished print.

The machine is further characterized b the fact that the sensitized sheets or` ca for use with the machineare carried in a package or cartridge which can readily be attached-to or detached from the mac ine pro r without" da r of accidentall exposing the sheets. t is thus possib e to make prints from the desired negative on any grade or kind of. per regardless of 'the number of sheets aready used from a cartridge by merely removing the cartridge in use and substituting another containin sheets of the proper grade and surface.v further advantage of' the present machine overthose us' a roll of sensitized aper, is that the sh ts or cards lie fiat and 'o not tend to cur While -poessing all the advantages of prior types of printing and developing ma- 4o chines which Yare quite cumbersome and require considerable space in which tobe set up, .the present device may readily be folded into compact V form for transportation and uickly 'setnp' for use whenever desired.V t is therefore especially-adapted to the usel of travelers ande campers, and others desiring to do their o wn printing and developing. f l y Other and further advantages of the 11' vention will appeal"` uponconsideration'` of the following description taken in conjunction with the accompanying drawings, in which,A -j Figure 1 represents a longitudinal-section A5l of the machine: with a of sen-vV folded or co apsed form with the cartridge sheets therein, and

The machine in general consists of a main compartment in which the sensitized sheets are printed and developed, a cartridge or package containin a supply of sensitized sheets to be fed to iihe printing and developing compartment, and a xing compartment into which the developed sheets are passed and from which they may. be removed when Referring to the drawings, 1 and 2 represent the members, preferably of wood, form' the4 front'and back respectively of the casing forming the printingand developing compartment. Member 2 1s pivotal y connected at its top'by suitable means 3 to side extensions 4 and 5 of front member 1, and at its lower edge to the casing whlch compartment 6 by means ylill forms twiki? ofi hinges 7. uitable"llght-pmcf` iiexible llo bis back members, 1 an 2,-of developin bers 25, t e-free ends of which are'adapted material 8, extending between members 1 and 2, forms the sides of the printing and developing compartment, so that the parts may be folded into collapsed form when desired, as shown in Fig. 7.A A collapsible strut 9 on either side of the rinting and developing compartment, and) extending between a'nd pivotally'connected at its ends to members 1 and 2, serves to maintain the lower ends of these members in proper po- A sition when the machine is set up for use.

An opening -10 is provided in front meniber 1 of the priiitin and developin compartment throu h w ich light is a mitted for rinting t e Vsensitized sheets. Remova ly mounted in opening 10 is a glass plate 11, secured on one side by clips 12 and on the other side'by catch 13 whereby plate 11 may be removed when desired. The negative 14, which is shown in roll form merely by way of,. example, is carried on spindles 15 and 16 removably mounted in suitable brackets 17 and 18, located respectively above and below opening 10. Negative 14 extends over openin 10 and behind glass 11, suitable spaces being left between the ends of the glass and the top and bottom of opening 10 for this purpose. When it is desired to use glass negatives instead of roll negatives, glass .11 may be removed and the desired'I negative readily substituted, if of proper size. If cut-film ne atives, or glass negatives smaller than opening 10, are used,-

a'suitable septum, secured in place by clips 12 and clamp 13, may be used to hold t e negative in' proper position. A. door 19 hinged to the face of member 1 serves when closed to exclude light from the printing andl developin lcom artment throu h o nin 10 when desired? g Pe g Removably attached to 'the' top of the printing and developing compartment is the cartrid e or package containing the suppl of sensitized sheets. This cartridge, whic is preferably made of cardboard, consists essentially of a box member 20 and a top 21, suitably. hinged'together at 22 and containing a series ofseiisitized sheets 23. When not in use, the cartrid e proper -is intended to beplacedin a suita le container 24, thus insuring against vaccidental yopening of the cartridge and exposure of the sensitized sheets.

' Provided'at the u per ed E printing and' compartment, are hinged memto slip under clips 26 provided on the outer faces of members\20 and 21 tief thelcartridge, whereby members 20 .and 21 are held in proper position to permit the feeding of sheets 23 to the printing mechanism. A

Y -lightproof` apron 27 vsecured at its lower edge to the printing and developing com- `partinentand provided at its upper edge `during the printing operation.

of front and with a resilient cord 28 to hold the apron in sheets` 23, extend from the lower part of iaiiember 20, where they are secured at 31, diagonally across the' faces of sheets 23, around strips 29 and out of the top of the cartridge at an opening 32 in member 20. It. will thus be seen that upon pulling one of the lcords 30, the corres riding strip 29 will be severed and the s eet 23 which it supports released, whereupon the sheet will fall through the lower end of box member 20 into the rint-ing compartment, as shown in Fig. 1. ln order to prevent the possible entrance of light through opening 32, a felt orpother pad 33, held in place by spring 34, is provided, which howeveriin no way interferes with the functioning-of cords 30. Cords further s erve| to revent all but the sheet about to be release i. e., the sheet towards the front of the machine, from swinging outward and thus interfering with the proper releasing of that sheet. A strip 35 secured to the sides'of member 20-prevents the sheet being released from swinging out and catchin on thevlower edge of cover 21. A suitab` e guide 36, secured to the rear face of member 1 above opening 10 and directly beneath the opening in the top of the printing and developing compartment through ywhich the sensitized sheets fall,

serves to direct each sheet 23, as it is released, to the printing mechanism.

Means are-provided within the printing and developing compartment at the rear of exposureV glass 11 for receiving sheets 23 as they are released and pressing them firmly against` negative 14 and exposureV glass 11 Journaled in side members 4 and 5 is a shaft 37 carrying rigidly-secured thereto a pair of downwardly extending arms 3.8.,y Pressure plate 39, which receives sheets 23 as they are released from the cartridge, is provided at its lower corners'with brackets 40 having pins 41 engaging slots 42 in the lower ends of arms 38, thus supporting thelower end of the pressure plate. Rotatabl mounted on shaft 37 is a yoke 43 carrying a pair of downwardly projecting arms 44 pivotally connected at their lower ends to brackets 45 secured atl the upper corners of plate 39,

-whereby the upper end offplate 39 is supported. A crank 46 on the end of shaft 37 and a similar crank 47 -on` the end of a tubular extension 48 on yoke 43 provide means outside the printing and developing compartment for swinging pressure plate 39 to' llO an)1 desired position. A catch 49 holds crank- 47 durin the rinting operation.

Secu toV the lower. edge .of plate 39 by Y means of springs 50 is a ledge 51 ada ted to catch sheets 23 when released from t e car- 'bridge and hold them in placeon plate 39.

It will thus be seen that when plate 39 is swung into position against negative 14, springs 50 will permit ledge 51 to swing back so as not to interfere with the proper functioning of the preure late.

The apparatus for deve oping the eX- posed sheets is located just beneath the printingI mechanism. Av tray 52 adapted to contain a suitable developing fluid is located in they lower part of the printing and de- 4all veloping compartment on the support upon which the machine rests. Overlying one end of tray 52 is a roller 53 having its shaft 54 .journ-alled in apair of blocks 55 pivotsecured to hinges 7. A crank 56 is provi edon the end of shafit 54 for rotating roller 53. A pair of brackets 57 secured to the inner face of front member 1 serves to support another and smaller roller 58 at the other end'4 and near the bottom of tray 52. Passing around rollers 53 and 58 is a series of resilient endless bands 59. Loosely mounted onshaft 54 of roller 53, isa yoke 60 provided with an extension 61 and a series of prongs 62 overlying endless bands A59. A crank 63-is provided on the end of a tubular extension 64 on yoke 60 whereby the yoke and its prongs 62 may be lrotated about shaft 54. i

Thus, it will be seen that, when an exposed sheet has fallen on endless bands 59,

the bands,'yoke 60 and its lprongs 62 bein i Y in the position shown in Fig. l, rotation o ing to the fixing apparatus,

crank 63 in a counter-clockwise direction will cause yoke 60 through extension 61 to depress the resilient bands 59 well beneath :the developing fluid in rtray 52, while prongs 62 descending with yoke .'60 serve "tosubmerge the sheet in the fluid, as shown in Fig. 2'.' Yoke 60 with ro 62 are then returned to theirv origina position by means of crank 63, thus allowing bands 59 to againl assume the position shown in Fig. 1, and thereby lift the print out of Ithe developing fiuid., A transparent plate 65 of suitable material is` provided in back member 2 of the printing and developin compartment whereby the operations inci ent to printing and developing may be observed without Located in the bottom of the fixi 0' oompartment 6 on the uppont on which the machine rests, is an her tray 66 adapted to contain a suitable fixing fluid. An opening 67 in the end of fixing compartment 6 rmits passage of the prints from the deve opas shown 1n Fig. 1. Handle 56 being turned clockwise,

the' print resting-on endless bends 59 will vbe carried over roller 53 through opening 67 into the fixing tray 66. A door 68 havin@ a handle 69 is provided in the top of the `x ing compartment 6 whereby prints may be removed from tray 66. In order to prevent communication between t-he printing and developing chamber and the fixing chamber when 'door 68 of the latter is open,5 a door 7() is provided for opening 67 which closes said opening when door 68 is raised, as in lVig. 2, and is automatically raised to permit the passage of developed prints to Vthe fixing compartment Ywhen door 68 is closed, as in Fig. 1. This is accomplished by means of a lever 71 loosely mounted on a shaft 72 journallcd in the sides of compartment 6,

lsaid lever having a weighted extension 73 -whereby the opposite end of the lever is kept constantly in engagement with the under side of door 68. A projection v74 on door is adapted to 'be engaged by the extension 73 of lever 71 to raise door l70 when door 68 is closed, as shown in Fig. 1, and to be disengaged 'from projection 74 to allow door 70 to close when door68 is open, as shown in Fig. 2.

The desired negative having been placed before opening 10 in member 1, and :a can fridge containing sensitized sheets of the proper grade and So forth, having been attached, the operations incident to the making of each finished print are substantially as follows v Pressure pla-te 39 is swung into the position shown 1n Fig. 1 by the proper manipulation of cranks 46 and 47, and door 19 closed in order to exclude light. from the developing and printing compartment. The first cord 30 towards `the front of the machine is then pulled, thereby severing the corresponding strip 29 and releasing the sheet 23 -supported by said strip; whereupon, the released sheet 23 slides into the printing and developing compartment, guided by Strip 35 and guide 36, on to pressure plate 39, the lower edge of sheet 23 resting on ledge 51. @ranks 46 and 47 are then manipulated again to bring pressure vplate 39 into the position shown in Fig. 2,

yupon the door is closed.

The exposedv sheet 23 being ready for developing, cranks 46 and 47 are manipulated to swing pressure plate 39 into the dotted line posltion shown in Fig. 2. f Sheet 2 3 will then slide from plate 39 over ledge 51 on to endless bands 59., Crank 63 .is then rotated to depress bands 59 through oke 60 and extension 61, while prongs 62 escend upon print 23 and force it beneath the surface of the developing fluid in tray 52 as shown in'Fig. 2.
